Protein Deacetylase Cobb Interplays with C-Di-Gmp

Bacterial c-di-GMP Is an Immunostimulatory

The characterization of a cyclic-di-GMP (c-Di-GMP) pathway leads to a new tool for studying c-Di-GMP metabolic genes.

Second messengers play an integral role in regulating a wide variety of pathways in response to triggers from the extracellular milieu. The intracellular second messenger cyclic diguanylate (c-di-GMP) has been shown to regulate microbial adaptation to extracellular environments in myriad ways. Primarily studied in Gram-negative bacteria thus far, c-di-GMP regulates motility, biofilm formation, ...

The Streptomyces master regulator BldD binds c-di-GMP sequentially to create a functional BldD2-(c-di-GMP)4 complex

Streptomyces are ubiquitous soil bacteria that undergo a complex developmental transition coinciding with their production of antibiotics. This transition is controlled by binding of a novel tetrameric form of the second messenger, 3΄-5΄ cyclic diguanylic acid (c-di-GMP) to the master repressor, BldD. In all domains of life, nucleotide-based second messengers allow a rapid integration of extern...

Localization of c-di-GMP-binding protein with the linear terminal complexes of Acetobacter xylinum.

Specific labeling of a single row of cellulose-synthesizing complexes (terminal complexes, TC subunits, TCs, or TC arrays) in Acetobacter xylinum by antibodies raised against a 93-kDa protein (the cyclic dignanylic acid-binding protein) has been demonstrated by using the sodium dodecyl sulfate (SDS)-freeze-fracture labeling (FRL) technique. The antibodies to the 93-kDa protein specifically reco...

Role of C-di-gmp Signalling in Bacterial-host Interactions

Bacteria have various ways to sense environmental signals and to adapt their behavior and physiology through different signaling systems. Secondary messenger signaling, amplified by enzymatic activity, rapidly transmits a signal in the cell resulting in allosteric functional control. Cyclic diguanosine monophosphate (c-di-GMP) is a novel global secondary messenger, that is found exclusively in ...
